Hi there! I have what may be a silly question about the intended usage of the TCP listener (./rtl_ais -T)

When I run rtl_ais in this mode, and connect a new client to the host and port (eg telnet localhost 10110), the client receives a burst of buffered messages, then nothing further. Sending a character from the client causes the connection to be closed.

What I'd expect: The client receives buffered messages, and continues to receive all newly-parsed messages, until either side terminates the connection.

Taking a look at docs and code, I can't quite see anything I'm doing wrong, so I'm thinking this is either intentional or perhaps just disused. Before I prep a PR, can you share any insight? Thanks for maintaining this!
